141 | 初始化默认的 `RxCache` 142 | ```java 143 | RxCache.initializeDefault(rxcache) 144 | ``` 145 | 再这样使用 146 | ```java 147 | observable 148 | .compose(RxCache.getDefault().<~>>transformObservable("custom_key", type, strategy)) 149 | ... 150 | ``` 151 | 如果不初始化默认的 `RxCache`，这样使用缓存会保存到 `Environment.getDownloadCacheDirectory()`
且 `appVersion` 会永远为 `1` 152 | 153 | 154 | ## Kotlin 155 | **推荐使用 kotlin** ，规避了泛型擦除，可不传 `type`, 无比简单 : 156 | 157 | ```kotlin 158 | observable 159 | .rxCache("custom_key", strategy) //这样会使用默认的 RxCache ，你也可以传入任意 rxcache 使用 160 | .subscribe(object : Observer> { 161 | ... 162 | } 163 | 164 | ``` 165 | 166 | 167 | 168 | 169 | 170 | 171 | ## 泛型 172 | 因为泛型擦除的原因，遇到 List<~> 这样的泛型时可以这样使用： 173 | 174 | ```java 175 | // <~> 为List元素的数据类型 176 | .compose(rxCache.>transformer("custom_key", new TypeToken>() {}.getType(), strategy)) 177 | ``` 178 | 179 | 没有泛型时 Type 直接传 Class 即可 180 | ```java 181 | .compose(rxCache.transformer("custom_key",Bean.class, strategy)) 182 | ``` 183 | 184 | **如果你使用 Kotlin 则没有这个问题** 185 | ```kotlin 186 | .rxCache(rxcache,"custom_key", strategy) 187 | ``` 188 | 189 | 190 | 191 | ## 基础用法 192 | 193 | ### 保存缓存： 194 | 如 保存字符串到内存和硬盘： 195 | ```java 196 | rxCache 197 | .save("test_key1","RxCache is simple", CacheTarget.MemoryAndDisk) 198 | .subscribeOn(Schedulers.io()) 199 | .subscribe(); 200 | ``` 201 | 保存方式提供了 3 种选择： 202 | ```java 203 | public enum CacheTarget { 204 | Memory, 205 | Disk, 206 | MemoryAndDisk; 207 | ... 208 | } 209 | ``` 210 | 211 | 212 | ### 读取缓存： 213 | 读取的顺序会按照内存-->硬盘的顺序读取 214 | 如 读取缓存中的字符串： 215 | ```java 216 | rxCache 217 | .load("test_key1", String.class) 218 | .map(new CacheResult.MapFunc()) 219 | .subscribe(new Consumer() { 220 | @Override 221 | public void accept(String value) throws Exception { 222 | 223 | } 224 | }); 225 | ``` 226 | 227 | 同步获取缓存： 228 | ```java 229 | CacheResult = rxCache.loadSync("test_key1", String.class); 230 | ``` 231 | 232 | 233 | 234 | ## 混淆配置 235 | 本 Library 不需求添加额外混淆配置，所以代码都可被混淆 236 | 237 | -------------------------------------------------------------------------------- /build.gradle: -------------------------------------------------------------------------------- 1 | // Top-level build file where you can add configuration options common to all sub-projects/modules. 2 | 3 | buildscript { 4 | ext.kotlin_version = '1.3.21' 5 | repositories { 6 | jcenter() 7 | maven { 8 | url 'https://maven.google.com/' 9 | name 'Google' 10 | } 11 | google() 12 | } 13 | dependencies { 14 | classpath 'com.android.tools.build:gradle:3.3.0' 15 | 16 | classpath 'com.github.dcendents:android-maven-gradle-plugin:2.0' 17 | classpath "guru.stefma.bintrayrelease:bintrayrelease:1.1.1" 18 | classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" 19 | // NOTE: Do not place your application dependencies here; they belong 20 | // in the individual module build.gradle files 21 | } 22 | 23 | } 24 | 25 | allprojects { 26 | repositories { 27 | jcenter() 28 | mavenCentral() 29 | maven { url "https://jitpack.io" } 30 | maven{url 'https://dl.bintray.com/zchu/maven/'} 31 | maven { 32 | url 'https://maven.google.com/' 33 | name 'Google' 34 | } 35 | } 36 | 37 | tasks.withType(Javadoc) { 38 | options{ encoding "UTF-8" 39 | charSet 'UTF-8' 40 | links "http://docs.oracle.com/javase/7/docs/api" 41 | } 42 | } 43 | /* gradle.projectsEvaluated { 44 | tasks.withType(JavaCompile) { 45 | options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation" 46 | } 47 | }*/ 48 | } 49 | 50 | task clean(type: Delete) { 51 | delete rootProject.buildDir 52 | } 53 | -------------------------------------------------------------------------------- /gradle.properties: -------------------------------------------------------------------------------- 1 | android.enableJetifier=true 2 | android.useAndroidX=true -------------------------------------------------------------------------------- /gradle/wrapper/gradle-wrapper.jar: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/z-chu/RxCache/f8ce1751508f1684ff68eb770e90f5f3208e30fd/gradle/wrapper/gradle-wrapper.jar -------------------------------------------------------------------------------- /gradle/wrapper/gradle-wrapper.properties: -------------------------------------------------------------------------------- 1 | #Fri Feb 15 13:36:39 SGT 2019 2 | distributionBase=GRADLE_USER_HOME 3 | distributionPath=wrapper/dists 4 | zipStoreBase=GRADLE_USER_HOME 5 | zipStorePath=wrapper/dists 6 | org.gradle.daemon=true 7 | distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip 8 | org.gradle.parallel=true 9 | -------------------------------------------------------------------------------- /gradlew: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env bash 2 | 3 | ############################################################################## 4 | ## 5 | ## Gradle start up script for UN*X 6 | ## 7 | ############################################################################## 8 | 9 | # Add default JVM options here.
